longitudinal rigidity

A dynamic memory allocation method for global stiffness matrix in FEM and its application to geotechnical engineering;

有限元法中总刚动态存取及其应用

Upon analyzing a typical building model with locally staggered floors,the use of global stiffness model results in the adequacy of effective mass participation factor.

通过一个典型的结构模型,对于结构存在局部错层时,采用"总刚模型"进行设计,结构有效质量系数总不满足要求的原因进行分析,并就此提出了一些有效的处理方法,以供设计人员参考。
